I think I've gotten FLAC__lpc_restore_signal() about as good as I'm going to
get it.
Here's what I have:
-a new file, lpc_asm.s, which has the assembly routines
-changes to cpu.h, cpu.c, and stream_decoder.c to enable them
-changes to configure.in to support the new cpu stuff
-a preliminary Makefile.am
-maybe something else I'm forgetting
Now automake complains that configure.in
